                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (Unaudited)

1. ORGANIZATION

   Aastrom Biosciences, Inc. (the "Company") was incorporated in March 1989
   ("Inception") under the name Ann Arbor Stromal, Inc. The Company changed its
   name in 1991 concurrent with the commencement of employee-based operations.
   The Company is in the development stage with its principal business
   activities being research and product development, conducted both on its own
   behalf and in connection with various collaborative research and development
   agreements with others, involving the development of processes and products
   for the ex vivo production of human cells for use in cell and ex vivo gene
   therapy.

2. BASIS OF PRESENTATION

   The condensed financial statements included herein have been prepared by the
   Company without audit according to the rules and regulations of the
   Securities and Exchange Commission. Certain information and footnote
   disclosures normally included in financial statements prepared in accordance
   with generally accepted accounting principles have been omitted pursuant to
   such rules and regulations. The financial statements reflect, in the opinion
   of management, all adjustments (which consist solely of normal recurring
   adjustments) necessary to present fairly the financial position and results
   of operations as of and for the periods indicated. The results of operations
   for the three and six months ended December 31, 1998, are not necessarily
   indicative of the results to be expected for the full year or for any other
   period.

   These financial statements should be read in conjunction with the audited
   financial statements and the notes thereto included in the Company's Annual
   Report on Form 10-K, as filed with the Securities and Exchange Commission.

3. NET LOSS PER COMMON SHARE

   Net loss per common share is computed using the weighted average number of
   common and common equivalent shares outstanding during the period. Common
   equivalent shares are not included in the per share calculation where the
   effect of their inclusion would be anti-dilutive. Upon the completion of the
   Company's initial public offering, all outstanding shares of preferred stock
   at that time were automatically converted into common stock. Accordingly,
   such shares of preferred stock are assumed to have been converted into common
   stock at the time of issuance.

   The computation of net loss per common share reflects dividends, yields and
   other adjustments relating to Company's preferred stock which affect only the
   computation of net loss per common share and are not included in the
   computation of net loss for the period.

                                       6

 
4. COMPREHENSIVE INCOME

   In June 1997, the Financial Accounting Standards Board issued Statement of
   Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
   ("SFAS 130"), which sets forth additional requirements for companies to
   report in the financial statements Comprehensive Income in addition to Net
   Income. The Company adopted SFAS 130 as of July 1, 1998 which did not have a
   material effect on the accompanying financial statements.

5. PREFERRED STOCK

   In December 1998, all 2,200,000 shares of the Company's 5.5% Convertible
   Preferred Stock were converted into 2,240,326 shares of common stock.
   Additionally, during November and December 1998, a total of 1,000 shares of
   the Company's Series I Convertible Preferred Stock were converted into
   458,043 shares of common stock.

6. DISTRIBUTION AGREEMENT

   In 1993 the Company entered into a product Distribution Agreement (the
   "Distribution Agreement") with Cobe BCT, Inc. ("Cobe"). The Distribution
   Agreement provided Cobe with worldwide marketing and distribution rights for
   the AastromReplicell/TM/ Cell Production System ("System") and related
   therapy kits for use in the field of stem cell therapy. The Company is
   implementing the initial European market introduction of the
   AastromReplicell/TM/ System and related therapy kits for the production of
   either bone marrow derived cells or the expansion of umbilical cord blood
   cells used in stem cell therapy. The Company believes that upon completion of
   AastromReplicell/TM/ System and European market introduction for stem cell
   therapy, development of additional therapy kits can be pursued for a number
   of emerging cell therapies being developed by others. Such other cell therapy
   applications were outside of the scope of the Distribution Agreement and
   outside of Cobe's area of focus. Accordingly, the Company and Cobe terminated
   the Distribution Agreement, effective November 16, 1998. In connection with
   the termination, Cobe paid $1,237,000 to the Company which has been recorded
   as Other Income in the accompanying Statements of Operations for the periods
   ended December 31, 1998. Cobe currently owns approximately 2.4 million shares
   of the Company's common stock, and as part of the termination agreement, Cobe
   has agreed not to sell any such shares until at least January 1, 2001. The
   Company believes that this action, which brings rights to all fields of use
   to the Company, will better allow for a consolidated marketing plan to be
   implemented for the AastromReplicell/TM/ System product line.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

OVERVIEW

Since its inception, the Company has been in the development stage and engaged
in research and product development, conducted principally on its own behalf,
but also in connection with various collaborative research and development
agreements with other entities. The Company does not expect to generate positive
cash flows from operations for at least the next several years and until product
sales commence. Until product sales commence, the Company expects that its
revenue sources will continue to be limited to grant revenue, research funding
and milestone payments and licensing fees from potential future corporate
collaborators. The timing and amount of such future cash payments and revenues,
if any, will be subject to significant fluctuations, based in part on the
success of the Company's research activities, the receipt of necessary
regulatory approvals, the timing of the achievement of certain other milestones
and the extent to which associated costs are reimbursed under grant or other
arrangements.  A substantial portion of all of the Company's revenues from
product sales, if any, will be subject to the Company's obligation to make
aggregate royalty payments of up to 2% to certain licensors of its technology.
Research and development expenses may fluctuate due to the timing of
expenditures for the varying stages of the Company's research, product
development and clinical development programs. Generally, product development
expenses for the AastromReplicell/TM/ System are expected to decrease as the
product progresses through market launch and clinical development costs are
expected to increase as the Company begins its U.S. pivotal clinical trials.
Additionally, marketing and general and administrative expenses are expected to
increase in support of European marketing activities.  In November 1998, the
Company implemented a reduction in work force, affecting 19 staff positions and
certain other contract positions, reducing overall operating expenses by
approximately 15%.  The reduction in headcount generally affected staff and
operations that were not required for product manufacturing and support or to
support the Company's clinical development programs.  Under the Company's
license agreement with Immunex, annual renewal fees of $1,000,000 are payable in
March 1999 and March 2000.   As a result of these and other factors, the
Company's results of operations have fluctuated and are expected to continue to
fluctuate significantly from year to year and from quarter to quarter and
therefore may not be comparable to or indicative of the result of operations for
any future periods.

Over the past several years, the Company's net loss has primarily increased,
consistent with the growth in the Company's scope and size of operations.
Although the Company reduced its workforce in November 1998, a future growth in
employee headcount may become necessary to address increasing requirements in
the areas of product and customer support, research, clinical and regulatory
affairs, quality systems and administration.  Assuming capital is available to
finance such growth, the Company's operating expenses will increase as a result.
At least until such time as the Company enters into arrangements providing
research and development funding or initiates product sales, the Company will
continue to incur net operating losses.   The Company has never been profitable
and does not anticipate having net income unless and until product sales
commence. Through December 31, 1998, the Company has accumulated losses of

                                       8

 
$64,184,000.  There can be no assurance that the Company will be able to achieve
profitability on a sustained basis, if at all.

RESULTS OF OPERATIONS

Three and six months ended December 31, 1998 and 1997
 
Revenues for the quarter and six-month periods ended December 31, 1998,
consisted of grant funding and increased to $207,000 and $370,000, respectively,
from $49,000 and $65,000, respectively in 1997. The increases in revenues during
1998 are the result of an in increase in research activities under research
grants received by the Company.

Costs and expenses decreased to $3,861,000 for the quarter ended December 31,
1998 from $4,671,000 for the same period in 1997, and decreased to $7,605,000
for the six-month period ended December 31, 1998 compared to $8,527,000 in 1997.
The decreases in costs and expenses were principally the result of decreases in
research and development expense to $3,165,000 and $6,258,000 for the quarter
and six months ended December 31, 1998, respectively, from $3,788,000 and
$7,031,000 for the same periods in 1997. General and administrative expenses
also decreased to $696,000 and $1,347,000 for the quarter and six months ended
December 31, 1998, from $883,000 and $1,496,000, for the same periods in 1997,
primarily as a result of certain non-cash charges incurred in 1997.

Interest income was $142,000 for the quarter ended December 31, 1998, compared
to $216,000 for the same period in 1997, and was $363,000 for the six months
ended December 31, 1998, compared to $436,000 for the same period ending in
1997.  These changes primarily reflect an overall decrease in the levels of
cash, cash equivalents and short-term investments during the periods.

Net loss for the quarter ended December 31, 1998 was $2,276,000, or $.16 per
common share, compared to a net loss of $4,408,000, or $.59 per common share for
the same period in 1997.  Net loss for the six months ended December 31, 1998
was $5,638,000, or $.42 per common share compared to $8,033,000, or $.87 per
common share in 1997.  The net loss for the periods ended December 31, 1998
include other income of $1,237,000 representing a one-time payment received from
Cobe in connection with the termination of the Company's marketing and
distribution agreement with Cobe in November 1998.  The computations of net loss
per common share for the periods ended December 31, 1997, reflect a one-time
charge of $3,439,000 related to the sale of preferred stock by the Company in
December 1997.  This one-time charge and dividends and yields on the Company's
preferred stock affect only the computation of net loss per common share and are
not included in the net loss for the periods.

Liquidity and capital resources

The Company has financed its operations since Inception primarily through public
and private sales of its equity securities, which from Inception through
December 31, 1998, have totaled approximately $74,419,000, and, to a lesser
degree, through grant funding, payments received under research agreements and
collaborations, interest earned on cash, cash equivalents, and 

                                       9

 
short-term investments, and funding under equipment leasing agreements. These
financing sources have historically allowed the Company to maintain adequate
levels of cash and other liquid investments.

The Company's combined cash, cash equivalents and short-term investments totaled
$10,852,000 at December 31, 1998, a decrease of $360,000 from June 30, 1998. The
primary uses of cash, cash equivalents and short-term investments during the six
months ended December 31, 1998, included $4,987,000 to finance the Company's
operations and working capital requirements, $62,000 in capital equipment
additions and $35,000 in scheduled debt payments. The Company plans to continue
its policy of investing excess funds in short-term, investment-grade, interest-
bearing instruments.

The Company's future cash requirements will depend on many factors, including
continued scientific progress in its research and development programs, the
scope and results of clinical trials, the time and costs involved in obtaining
regulatory approvals, the costs involved in filing, prosecuting and enforcing
patents, competing technological and market developments, the cost of product
commercialization and the degree of market acceptance of the Company's products.
The Company does not expect to generate a positive cash flow from operations for
at least the next several years due to continuing expenses for its research and
development programs and the expected cost of commercializing its product
candidates.  The Company intends to seek additional funding through research and
development agreements with suitable corporate collaborators, grants, public or
private financing transactions and other means that may be available to the
Company.  The Company anticipates that its available cash resources and expected
interest income thereon, will be sufficient to finance the development and
manufacture of the AastromReplicell/TM/ System for use in clinical trials,
expand its clinical trials, and to fund other research and development and
working capital and other corporate requirements through mid-1999.  This
estimate is a forward-looking statement based on certain assumptions which could
be negatively impacted by the matters discussed under this heading and under the
caption "Business Risks" in the Company's Annual Report on Form 10-K.  The
Company expects that its primary sources of capital for the foreseeable future
will be through collaborative arrangements and through the public or private
sale of its debt or equity securities.  There can be no assurance that such
collaborative arrangements, or any public or private financing, will be
available on acceptable terms, if at all, or can be sustained. Several factors
will affect the Company's ability to raise additional funding, including, but
not limited to, market volatility of the Company's common stock and economic
conditions affecting the public markets generally or some portion or all of the
technology sector.  If adequate funds are not available, the Company will be
required to further delay, reduce the scope of, or eliminate one or more of its
research and development programs, or curtail some or all or its operations,
which would have a material adverse effect on the Company's business.  See
"Business Risks  Future Capital Needs; Uncertainty of Additional Funding" in the
Company's 1998 Annual Report on Form 10-K and Notes to Financial Statements
included therein.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting  Standards No. 130, "Reporting Comprehensive Income" ("SFAS
130"), which sets 

                                       10

 
forth additional requirements for companies to report in the financial
statements Comprehensive Income in addition to Net Income. The Company adopted
SFAS 130 as of July 1, 1998 which did not have a material effect on the
accompanying financial statements.

CERTAIN BUSINESS CONSIDERATIONS

Product Development Uncertainties

Commercialization of the Company's technology and product candidates, including
its lead product candidate, the AastromReplicell/TM/ Cell Production System
("System"), will require substantial additional research and development by the
Company as well as substantial clinical trials.  There can be no assurance that
the Company will successfully complete development of the AastromReplicell/TM/
System or its other product candidates, or successfully market its technologies
or product candidates, which lack of success would have a material adverse
effect on the Company's business, financial condition and results of operations.
The Company or its collaborators may encounter problems or delays relating to
research and development, market development, clinical trials, regulatory
approval and intellectual property rights of the Company's technologies and
product candidates.  The Company's initial product development efforts are
primarily directed toward obtaining regulatory approval to market the
AastromReplicell/TM/ System as an alternative, or improvement, to currently used
stem cell collection methods.  These existing stem cell collection methods have
been widely practiced for a number of years, and there can be no assurance that
any of the Company's technologies or product candidates will be accepted by the
marketplace as readily as these or other competing processes and methodologies,
or at all.  The Company also plans to pursue through strategic relationships,
clinical applications of the AastromReplicell/TM/ System into emerging cell
therapies being developed by others.  There can be no assurance that such
strategic relationships, if established, will successfully lead to commercial
applications of the AastromReplicell/TM/ System.

Termination of Cobe Distribution Agreement

In 1993 the Company entered into a product Distribution Agreement (the
"Distribution Agreement") with Cobe BCT, Inc. ("Cobe").  The Distribution
Agreement provided Cobe with worldwide marketing and distribution rights for the
AastromReplicell/TM/ Cell Production System ("System") and related therapy kits
for use in the field of stem cell therapy.  The Company is implementing the
initial European market introduction of the AastromReplicell/TM/ System and
related therapy kits for the production of either bone marrow derived cells or
the expansion of umbilical cord blood cells used in stem cell therapy.  The
Company believes that upon completion of AastromReplicell/TM/ System and
European market introduction for stem cell therapy, development of additional
therapy kits can be pursued for a number of emerging cell therapies being
developed by others.  Such other cell therapy applications were outside of the
scope of the Distribution Agreement and outside of Cobe's area of focus.
Accordingly, the Company and Cobe terminated the Distribution Agreement,
effective November 16, 1998.  In connection with the termination, Cobe paid
$1,237,000 to the Company which has been recorded as Other Income in the
accompanying Statements of Operations for the periods ended December 31, 1998.
Cobe currently owns approximately 2.4 million shares of the Company's common
stock, and as part of the termination agreement, Cobe has agreed not to sell any
such shares until 

                                       11

 
at least January 1, 2001. Thereafter, sale of the shares into the market could
effect the price of the Company's common stock. The Company believes that
termination of the Distribution Agreement, which brings rights to all fields of
use to the Company, will better allow for a consolidated marketing plan to be
implemented for the AastromReplicell/TM/ System product line. The
AastromReplicell/TM/ System consists of an automated clinical system designed to
enable hospitals to produce patient-specific cells for use in the treatment of a
broad range of diseases. The Company believes that with diverse fields of use,
the overall market development and customer interface plans will benefit from
the consolidation of the product line under disease-specific programs. There can
be no assurance that the Company will be able to enter into a new marketing and
distribution relationship on acceptable terms with another partner, if at all,
or that if such a marketing and distribution partnership is achieved, it will
result in the successful commercialization and distribution of the Company's
technologies and product candidates. Failure to enter into such a new
relationship, and any delay in the planning or implementation of distribution or
marketing activities while a new partnership is sought, will have a material
adverse effect on the Company's business, financial condition and results of
operations.

Uncertainties of Clinical Trials

The approval of the United States Food and Drug Administration (the "FDA") will
be required before any commercial sales of the Company's product candidates may
commence in the United States.  The Company is currently conducting clinical
trials to demonstrate the safety and biological activity of cells produced in
the AastromReplicell/TM/ System in a limited number of patients. If the results
from these trials are successful, the Company intends to use these results to
support a limited market introduction of the AastromReplicell/TM/ System in
Europe and to seek clearance from the FDA to commence additional pivotal
clinical trials in the U.S., the first of which began in December 1998.  The
patients enrolled in these trials and future trials will have undergone
extensive chemotherapy or radiation therapy treatments prior to infusion of
cells produced in the AastromReplicell/TM/ System.  Such treatments will have
substantially weakened these patients and may have irreparably damaged their
hematopoietic systems.  Due to these and other factors, it is possible that
these patients may die or suffer severe complications during the course of the
current trials or future trials.  For example, in the trials to date, some of
the patients who have been in the transplant recovery process have died from
complications related to the patient's clinical condition that, according to the
physicians involved, were unrelated to the AastromReplicell/TM/ System
procedure. The Company may experience delays in patient accruals in its current
clinical trials or in future clinical trials, which could result in increased
costs associated with the clinical trials or delays in receiving regulatory
approvals and commercialization, if any.  The results of preclinical studies and
early clinical trials of the Company's product candidates may not necessarily be
indicative of results that will be obtained from subsequent or more extensive
clinical trials.  Further, there can be no assurance that pre-pivotal or pivotal
clinical trials of any of the Company's product candidates will demonstrate the
safety, reliability and efficacy of such products, or of the cells produced in
such products, to the extent necessary to obtain required regulatory approvals
or market acceptance. There can be no assurance that, even after the
expenditures of substantial time and financial resources, regulatory approval
will be obtained for any products developed by the Company.

                                       12

 
European Regulatory Matters

The AastromReplicell/TM/ System components, are currently being regulated in
Europe as Class I Sterile or Class IIb medical devices, under the authority of
the new Medical Device Directives ("MDD") being implemented by European Union
("EU") member countries. In order for the Company to market its products in
Europe, it must obtain permission from a Notified Body to affix the CE Mark
which certifies that the Company and its operations comply with certain minimum
quality standards and compliance procedures, or, alternatively, that its
manufactured products meet a more limited set of requirements. Additionally, the
Company may be required to comply with certain country-specific regulations in
order to market its products.  The Company has received approval to affix the CE
Mark to the AastromReplicell/TM/ System instrumentation platform and the various
components of its SC-I Therapy Kit for the production of bone marrow derived
cells and CB-I Therapy Kit used for expansion of umbilical cord blood cells.
While initial approvals have been obtained, there can be no assurance that the
Company and its suppliers will be able to meet the minimum requirements
necessary to maintain such compliance.   Upon the completion of production-level
manufacturing and the Company's product release procedures, the CE Mark will
permit market introduction of the AastromReplicell/TM/ System in the EU.  The
inability to complete the transition to production-level manufacturing of the
AastromReplicell/TM/ System or non-compliance with the ongoing regulatory
requirements to permit commercialization would have a material adverse effect on
the Company's business, financial condition and results of operations.  Further,
there can be no assurance that the AastromReplicell/TM/ System will continue to
be regulated in Europe under its current status.  If the AastromReplicell/TM/
System is not so regulated, the Company could be forced to obtain additional
regulatory approvals and could be subject to additional regulatory requirements
and uncertainty, which would have a material adverse effect on the Company's
business, financial condition and results of operations.

Dependence on Third Parties for Materials

The Company currently arranges for the manufacture of its product candidates and
their components, including certain cytokines, serum and media, with third
parties, and expects to continue to do so for the foreseeable future.  There can
be no assurance that the Company's supply of such key cytokines, components,
product candidates and other materials will not become limited, be interrupted
or become restricted to certain geographic regions.  There can also be no
assurance that the Company will be able to obtain alternative components and
materials from other manufacturers of acceptable quality, or on terms or in
quantities acceptable to the Company, if at all.  Additionally, there can be no
assurance that the Company will not require additional cytokines, components and
other materials to manufacture, use or market its product candidates, or that
necessary key components will be available for use by the Company in the markets
where it intends to sell its products.  In the event that any of the Company's
key manufacturers or suppliers fail to perform their respective obligations or
the Company's supply of such cytokines, components or other materials becomes
limited or interrupted, the Company would not be able to market its product
candidates on a timely and cost-competitive basis, if at all, which would have a
material adverse effect on the Company's business, financial condition and
results of operations.  Certain of the compounds used by the Company in its
current stem cell 

                                       13

 
expansion process involve the use of animal-derived products. The availability
of these compounds for clinical and commercial use may become limited by
suppliers or restricted by regulatory authorities, which may impose a potential
competitive disadvantage for the Company's products compared to competing
products and procedures. There can be no assurance that the Company will not
experience delays or disadvantages related to the future availability of such
materials which would have a material adverse effect on the Company's business,
financial condition and results of operations.

History of Operating Losses

The Company is a development stage company and there can be no assurance that
its product candidates for cell therapy will be successful.  The Company has not
yet completed the development and clinical trials of any of its product
candidates and, accordingly, has not yet begun to generate revenues from the
commercialization of any of its product candidates.  The Company expects to
incur significant operating losses until commercialization of its product
candidates, primarily owing to its research and development programs, including
pre-clinical studies and clinical trials.  The development of the Company's
products will require the Company to raise substantial additional funds or to
seek collaborative partners, or both, to finance related research and
development activities.  Because of the Company's potential long-term funding
requirements, it may attempt to access the public or private equity markets if
and whenever conditions are favorable, even if it does not have an immediate
need for additional capital at that time.  There can be no assurance that any
such additional funding will be available to the Company on reasonable terms, or
at all. Several factors will affect the Company's ability to raise necessary
additional funding, including market volatility of the Company's stock and
economic conditions affecting the public markets generally or some portion or
all of the technology sector.  If adequate funds are not available, the Company
will be required to delay or terminate research and development programs,
curtail capital expenditures, and reduce or terminate business development and
other operating activities.

Year 2000 Issues

Many currently installed computer systems and software products are not capable
of distinguishing 20th century dates from 21st century dates.  As a result, in
less than one year, computer systems and/or software used by many companies in a
wide variety of applications will experience operating difficulties unless they
are modified or upgraded to adequately process information involving, related
to, or dependent upon the century change.  Significant uncertainty exists in the
software and information services industries concerning the scope and magnitude
of problems associated with the century change.  In light of the potentially
broad effects of the year 2000 on a wide range of business systems, the Company
may be affected.  The Company utilizes and is dependent upon data processing
computer hardware and software to conduct its business.  The Company has
completed its assessment of its own computer systems and based upon this
assessment, the Company believes its computer systems are substantially "Year
2000 compliant;" that is, its computer systems are capable of adequately
distinguishing 21st century dates from 20th century dates.  However, there can
be no assurance that the Company has timely identified or will timely identify
and remediate all significant Year 2000 problems in its own computer systems,
that remedial efforts subsequently made will not involve significant time and
expense, 

                                       14

 
or that such problems will not have a material adverse effect on the Company's
business, operating results and financial condition. The Company has yet to
determine the extent, or completed activities to minimize the risk, that the
computer systems of the Company's suppliers and manufactures are not Year 2000
compliant, or will not become compliant on a timely basis. The Company expects
that the process of making inquiries with these suppliers will be ongoing
through the end of 1999. If Year 2000 problems prevent any of the Company's
suppliers from timely delivery of products or services required by the Company,
the Company's operating results could be materially adversely affected. The
Company currently estimates that its costs to address the Year 2000 issue
relating to its suppliers will not be material, and that these costs will be
funded from its operating cash flows. To the extent practical, the Company
intends to identify alternative suppliers and manufactures in the event its
preferred suppliers become incapable of delivering products or services required
by the Company on a timely basis. The Company's estimates of Year 2000 costs
relating to its suppliers and manufactures are management's best estimates,
which were derived from numerous assumptions of future events, including the
continued availability of certain resources, third party remediation plans with
regard to Year 2000 issues, and other factors. There can be no assurance that
these estimates are correct and actual results could differ materially from
these estimates.

Private Equity Financing

In July 1998 the Registrant sold 5,000 shares of its newly created 1998 Series I
Convertible Preferred Stock (the "Series I Preferred") to one investor for an
aggregate purchase price of $5 million. The shares of Series I Preferred are
convertible, at the option of the holder, into shares of the Company's common
stock at the lower of  (i) $4.81, or (ii) a price based on the market price of
the Company's common stock prior to conversion.  With limited exceptions, the
shares of Series I Preferred are not convertible into common stock until April
1999 and, subject to extension under certain circumstances, will automatically
convert into common stock on July 2, 2001, unless sooner converted. As of
December 31, 1998, 4,000 shares of Series I Preferred remain outstanding.  In
general, the Company may require the holders to convert the Series I Preferred
if the average closing bid price of the Company's common stock exceeds $9.62 for
specified periods beginning in July 1999.  In connection with the sales of
Series I Preferred, the investor agreed to purchase an additional $3 million of
a new series of Preferred Stock (to be designated 1998 Series II Convertible
Preferred Stock) if the common stock of the Company trades at a price greater
than $6.00 for a specified duration during the period ending in August, 1999.

These business considerations, and others, are discussed in more detail and
should be read in conjunction with the Business Risks discussed in the Company's
Annual Report of Form 10-K.

Item 1.  Legal Proceedings

           None.

Item 2.  Changes in Securities and Use of Proceeds

           (c) In December 1997, the Company issued 2,200,000 shares of its 5.5%
               Convertible Preferred Stock ("5.5% Preferred Stock") in a
               registered direct placement at a price of $5.00 per share. In
               December 1998, all 2,200,000 shares of the 5.5% Preferred Stock
               were converted into 2,240,326 shares of common stock. The shares
               of common stock issued upon conversion were issued in a
               transaction exempt from the registration requirements of the
               Securities Act of 1933 by reason of Section 3(a)(9) thereof.
               These shares were issued to existing security holders upon
               conversion of outstanding securities of the Company in a
               transaction where no commission or other remuneration was paid
               directly or indirectly in connection with such exchange.

               In July 1998 the Registrant sold 5,000 shares of Series I
               Preferred. The shares of Series I Preferred are convertible, at
               the option of the holder, into shares of the Registrant's common
               stock at the lower of (i) $4.81, or (ii) a price based on the
               market price of the Registrant's common stock prior to
               conversion. The Company has issued 458,043 shares of common
               stock, upon the conversion of 1,000 shares of Series I Preferred.
               The shares of common stock issued upon conversion were issued in
               a transaction exempt from the registration requirements of the
               Securities Act of 1933 by reason of Section 3(a)(9) thereof.
               These shares were issued to existing security holders upon
               conversion of outstanding securities of the Company in a
               transaction where no commission or other remuneration was paid
               directly or indirectly in connection with such exchange.
